How do you classify a triangle by its side measurements​

If the side measurements of a trainable are all the same, the triangle is equilateral

if two of the sides are the same but the third isn’t, the triangle is isosceles

if all sides of a triangle have different measurements, the triangle is scalene

First step is to get rid of the square root. remember that a square root is the same as raising to the (1/2) power. see below: multiply exponents per exponent rules to get: remember you subtract exponents from the denominator and add exponents in the numerator so: simplify further: so a is the correct choice. if you don't understand this google exponent rules and it will you understand. look at the image results.
